' SEPARABLE FASTENEB.

To all whom it may concern.

Be it known that I, WILLIAM a citizen of the United States, residing at Waterbury, in the county of Waterbury, State of Connecticut, have invented certain new and useful Improvements in Separable Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to separable fasteners.

The object of the invention is to provide a. separable fastener which is particularly adapted for use upon carriage and automobile curtains, and heavy goods of various kinds. In carrying out the invention it is intended to provide a button having a secure mounting, by which the fabric is evenly held and the strain thereon isevenly distributed.

Furthermore, it is the object of the invention to provide a fastener of neat appearance, and one capable of suitable ornamentation and finish.

l/Vith the above objects in view, and such others relating to the details of construction, as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure l is a view of the device in use,

Fig. 2 is a rear view thereof,

Fig. 3 is arear view of the device removed from the fabric,

Fig. 4 is a view of the device with the back plate removed, and

Fig. 5 is a section through the device in its applied position.

Referring more particularly to the drawings, 1 represents a cap plate or body which has an annular flange 2 and a central depression 0r dome 3. The annular flange 2 provides a seat which confines a spring retaining member 4. The spring retaining member 4 consists of an annulus 5 which is expanded against the flange 2, and a pair of arms 6 which extend across thebase of the dome 3 in spaced and slightly divergent relation. Crimped or otherwise secured within the edge of the flange 2 is a closure plate 7 which has a socket opening or re cess 8 registering with the dome 3 and is Specification of Letters Patent.

furthermore surrounded by an outwardly turned flange 9. Also, the closure plate 7 is plate in position and properly clamp the fabric, the prongs 10 entering the goods or fabric to revent relative rotation of the fastening cevice. r

The socket member thus provided is shaped to receive the complementary male member 12, the latter being a headed projection having an annular groove which will receive the spring arms of the resilient member 4. The head of the member 12 is so shaped that it may readily pass between the sides of the spring retaining member, until the latter snap into the annular groove, and the conformation is furthermore such that the arms of the spring member may be sprung apart by pulling upon the separable members of the fastener. If desired, the face of the plate 1 may be apertured adjacent the contracted portion of the spring arms of the retaining member, so that if it I is necessary, an instrument may be inserted therebetween to assist in the operation of the members should they fit together too tightly.

It will be apparent from the foregoing description that I have provided .a very simple and effective separable fastener which is equally adapted for use on automobile or other vehicle curtains, or upon uniforms and heavy garments. The form of the headed or male member is shown adapted for insertion in a vehicle body,but it is obvious that a different form of attaching device may be supplied without departing from the spirit of my invention.

What I claim as my invention is A separable fastener, comprising in combination, a socket member comprising a comparatively wide plate having a dome rising from its center, a flange on the plate extending in the opposite direction to said dome, a spring retaining member contacting said flange throughout its inner surface and having resilient arms extended across the dome, a plate apertured to register with the con cavity of the dome and secured within the flange and to have the latter swaged there- 10 free edge of the flange surrounding the first over.
